The manga started very promising and unique. To unravel the mysterious symbols that represented the supporting character's past was very clever and satisfying. The movement of the homunculi were very fluid and interesting for each representation. All characters were very well though out and multi-dimensional. However, when we've come to the main character's own personal history towards the end, the pace felt very slow and repetitive and the ending very meh for the tension that's been built up. It just didn't come all together at the end, and it left me wondering what the entire story was supposed to leave me know or understand.
Absolutely loved the author's tension building and characterizations through the homunculi. Fell extremely short on the ending.
